COMB.

Specification of Letters Patent.

Patented May 18, 1920.

Application filedNovember 19, 1918. Serial No. 263,131.

To all whom it may concern Be it known that I, JOSEPH A. CYPERT, acitizen of the United States, residing at Kansas City, in the county ofJackson and State of Missouri, have invented certain new and usefulImprovements in Combs, of which the following is a full, clear, andexact description, such as will enable others skilled in the art towhich it appertains to make and use the same.

The invention relates to combs and more particularly to a comb to beemployed by barbers and others in connection with cutting the hair ofpersons.

In cutting hair it is desirable to cut the hair short near the neck ofthe person and gradually leave the hair longer as the crown of the headis approached. The ordinary comb is usually provided with a square orround edge opposite the teeth, which does not admit of the smoothrolling motion that is necessary to adjust the comb from a position thatwill produce a short length of hair near the neck and a gradually longerlength as the crown of the head is approached. It is understood that thehair is cut with scissors or clippers close to the side of the combopposite the head from which the hair is cut.

As the barber starts to cut the hair near the neck and cuts upward, thesquare corner or round edge of the ordinary comb is first on the personsneck and then on the mat of uncut hair. The comb does not feel pleas antto the person whose hair is being out, and the uncut hair does not forma smooth bearing for a square or small round corner.

The present invention has provided an improved comb with the back edgeopposite the teeth beveled and forming an arc whose chord lies in anacute angle to the axis of the teeth, presenting a'wide smooth rollingsurface to the neck and to the hair over which the comb is passed in arolling motion in the operation of cutting a persons hair.

By presenting a broad curved surface to the persons neck and hair thecomb is not unpleasant to the neck and the hair forms a bearing surfaceover which the comb may be easily moved in a rolling motion, whereas asharp corner or a round edge does not present sufficient surface toslide evenly over the hair.

l/Vith these and other objects in view,the invention consists in thefeatures of construction, form, and combinations of forms hereinafterset forth, the accompanying drawings illustrating acomb in which theimproved features are embodied.

In the drawings Figure 1 is a side view of a comb in which the improvedfeatures are embodied.

Fig. 2 is a view of the opposite side of the comb from that shown inFig. 1. V

Fig. 3 is an enlarged sectional view taken on line 3-3 of Fig. 1 andline 33 of Fig. 2.

Fig. 4 is an enlarged sectional view taken on line el-4t of Fig. 1 andline 4-4 of Fig. 2.

The comb 5 is of ordinary form and construction with the usual coarseteeth 6 and fine teeth '7, excepting that the side 8 from the end 9 tothe intersection of the coarse and fine teeth at 10 is beveled to formthe curve 11 preferably irregular from 12 to 13, while the side 14.-from the end 15 to the intersection 10 of the coarse and fine teeth isbeveled to form the curve 16 preferably irregular from 17 to 18.

When the coarse teeth 6 of the comb are employed the teeth are startedupward into the hair from the neck of the person with the side 8 restingon the neck, and the comb is gradually rolled with the teeth sideoutward from the hair until the curved portion 11 rests first upon theneck and then on the hair as the comb advances upward through the hair,and no matter to what angle the comb is inclined from the hair thecurved portion 11 forms a smooth steady resting surface for the comb.The opposite end of the comb is employed in the same manner withreference to the form thereof.

The improved comb is very advantageous in connection with cutting thehair of per-.

sons, as the hair can be cut more evenly and in very much less time, sothat the comb improves the quality of the work and saves considerabletime, enabling the barber to out a persons hair in one third the timerequired when the ordinary comb is employed.

As a further advantage of the particular form of the comb, when theteeth 6 are employed the portion of the comb containing the teeth 7 isgrasped in the hand, and passing the teeth 6 upward through the hair hasa tendency to bend the end 9 of the comb downward. The curve 11decreases the quantity of material that would otherwise form the side'8of the comb and this side is in compression during the foregoingoperation, while the curve increases the quantity of material that wouldotherwise form the side 14 of the bar shaped back of the comb and thisside is in tension, so that with a given quantity of material the combis tougher and possesses greater stiffness than a comb with a square orround back edge. The same conditions are true with reference to theopposite end of the comb when the teeth 7 are employed. So that with agiven quantity of material the comb is stiffer and stronger againstbending stress by reason of the curves 11 and 16.

hat is claimed as new, and desired to secure by Letters Patent, is 1- 1.A comb with the back edge thereof beveled transversely in oppositedirections from near the center of the length of the combl'ongitudi-nallyto each end of the comb, each of the bevels forming anarc whose chord lies in an acute angle to the axis of the 2 teeth.

2. comb comprising an approximately straight flat bar-shaped back withconventional teeth projecting from one edge of the back, eachlongitudinal halfot the length 2 of the opposite edge: of thebackv ofthe comb beveled to. an arc; whose chord lies in an acute angle to theaxis of the; teeth.
